LIGHTING FIXTURE.

Application iled February 26, 1923.

To all whom t may concern.'

l-e it known that LFAUL C. loAN, a citizen of the United States,residing at Mount Vernonq in the county ol lllestchester and State ofllew York, have invented an lmprovenient inLighting Fixtures, of whichthe following is a speciication.

My invention relates generally to electric light fixtures and moreparticularly to means for supporting the globes or other Jforms ofshades inade use of in such fixtures.

rPhe object oi' my invention is to provide a screwless holder with meansfor supporting the shade or globe in such manner that itis impossiblefor it to tall accidentally, but which may be easily placed in position,or unlocked and removed, when desired, for cleaning or other purposes.

In carrying out my invention I make use or a screwless holder or socketcover in which are hung a plurality of globe supporting legs, in suchmanner that before the globe is placed in position they are uniformlybalanced in a position to allow their lower ends to enter the opening inthe shade or bowl when the neck of the bowl is inserted within the baseof the holder, and by the employment of a clamping ring surrounding theholder above its base and acting upon the project-ing upper ends of suchlegs, said lower ends oli said supporting legs are swung out-ward andinto contact with the interior surface of the bowl below its rim and scfcurely held in such position when the said clamping ring is pusheddov-Jn upon the upper surface ot the base or lower part of said holder.

The details of the invention are hereinafter particularly described.

ln the accompanying drawing:

Figure 1 is an elevation of a lighting lixture embodying my invention,partly in section and with the holder or socket cover, clamping ring andbowl broken away, showing the parts assembled but in unlocked position.

Fig. 2 is a similar view showing the parts in locked position, and

Fig. 3 is a top view of the holder, the globe supporting legs andclamping ring being removed.

Referring to the drawing indicates the holder or socket cover, providedwith an integral enlarged bottom 11, in the top of which a plurality ofspaced slots 12, are

made, preferably three, as shown mostclearly in Fig. 3.

13 denotes the globe supporting legs, which are preferably cut out of aflat piece of metal and bent up to the shape shown in Figs. 1 and 2.These legs are at a pre* determined point below their upper ends offsetas at 14, below which they are oit a thickness and width slightlysmaller than the slots 12 in the holder 10, through which they arepassed, the shoulder formed by the offset 14, seating upon the top ofthe holder in such manner as to permit a forward and backward movementof the legs. Three ol these legs 13, are preferably employed, and whenthey are in position in the holder 10. they are uniformly balanced, sothat before the parts are locked together they assume the position shownin Fig. 1, in which position it will be readily seen, that when theshade or globe 15, is placed into the bottom 11 of the holder, theselegs will pass through the opening in the globe, their lower endsclearing the rim of the bowl, but to avoid any possibility of the endsof the legs catching upon the rim of the bowl, l preferably bend thelower end of each leg downwardly and slightly inwardly, forming a guide16 at this end of each of the legs 13.

17 denotes a clamping ring litting over the socket cover 10, andprovided at its bottom with a concave skirt 18. This ring 17 is movablevertically ugon the socket cover, and acts upon the upper ends of theglobe supporting legs 13 to swing their lower ends outward and intoContact with the interior surface of the globe 15, below its neck orrim,

ln assembling the parts, the globe, bowl or shade 15, is placed withinthe bottom 11 ot the holder 10, as shown in Fig'l in doing which, thelower ends ot the legs 13 drop into the bowl as betore described. Theclamping ring 17 is then pushed downward over the upper ends of the legs13, these ends of the legs first passing under the concave skirt 18 ofthe ring 17 by which they are guided into the vertical portion of thering which in turn presses them into a vertical position against thesocket cover, at the same time swinging the lower ends of the legsoutwardly into contact with the inner surface of the globe as shown in2. llVhen the clamping ring 17 is fully dcpressed as shown in Fig. 2,the globe supporting legs 13, are securely held in the position shown insuch figure and when the holder is suspendedby a chain or other de-Vvice connected to the ring 19, the globe and holder cannot accidentallybecome separated, it being necessary to raise the clamping ring in orderto release the bowl. Y

While the skirt 18, of the ring 17 extends sufficiently over the upperends of the legs 13, in assembling the parts to pass over such ends, 1prefer to bend the upper end oie-ach leg inward as atv 20, to preventany possibility of any one of the legs passing outside said skirt whenthe clamping ring is lowered.

In order to render the device fool-proof, l prefer to provide means forpreventing the lifting of the binding ring 17 'through carelesshandling.` after the parts have been assen'ibled, and tor this purpose lcut out the upper inturned rim of the clamping ringl?, at two oppositepoints, and turn up the cut out portions at right angles at one end ofeach opening forming stops 21, the openings or slots 22, thus formed inthe rim ot Jthe ring 17, being passed over projections or lugs 23, onthe socket cover 10, when the ring 17 is placed in position.

These projections or lugs 23 may be formed on the socket cover 10, bycutting out tongues and bendingthem outward at right angles as shown inFigs. 1 and 2, or they may be simply pressed out in forming the shell.

lVhen the clamping ring 17 .is pushed down into the position shown inFig. 2,V the lugs 23, pass through the openings or vslots 22, when bygiving the ring 17, a partial ro- Y tation its rim will pass under thelugs 23, which eectually prevents the ring 17 being raisedunintentionally or by careless handling.

The ring may be given a half rotation which will bring the stops 21,against the lugs 23, and prevent further rotation of the ring in thatdirection, preventing its being lifted luntil. it has been rotated inthe opposite direction sufficiently far to bring the openings or slots22, in alignment with the lugs 23.

It will be seen that Vmy invention provides a simple and efficientscrewless type oi support for a bowl, globe or shade in lightingpiixtures, and by which the assembling or unplurality of spacedslots,globe supporting legs hung in said slots, and a clamping ring actingupon the upper ends of said legs Vto swing their lower ends outwardly.

2. A device ot' the character described, comprising a socket coverprovided with a plurality of spaced slots, globe supporting legs hung insaid slots, a clamping ring slidable upon said socket cover and by meansof which the lower ends of said legs may be swung outwardly, and meansfor preventing the accidental vertical movement of said clamping ringwhen the parts are assembled for use.

3. In a lighting iXture, the combination of a shell adapted to cover alamp socket, and provided with a plurality of spaced slots, globesupporting legs hung inV said slots, a bowl or shade having its neckwithin the lower part of said shell, and a clamping ring acting upon theupper part of the said legs to swing their lower ends into contact withthe inner surface'of the bowl.

Signed by me this 16th day of February, 1923.
